Got a quick question:
I am trying to run scripts in Red Hat 9.0, I include the #!/bin/bash directive, so I try to run the script my typing its name, nothing. If I type "bash script_name" it will run fine. Any way to get around the bash command?
I do not get any error, it just hard returns back to by prompt. I set the file permission to 777, and I am in the correct directory. The ./ worked...I thought there was a way to make it work by just typing the file name...am I wrong?
To be more precise, you either need to specify the directory where the script is (e.g. ./your_script, or /home/yourname/your_script, etc.) or put it in a directory listed in the PATH environment variable (seperated by colons ':'). Normally the directories /usr/local/bin:/usr/bin:/bin are in the PATH var. This is arranged by your distribution. To see the directories where the shell will find the script by itself through the PATH var, type:
If you put your script in one of the directories you see, you can just type its name (without ./ ).
You can also include a directory of your choice to the PATH var, say the directory "myscripts" in your home directory. Make sure this dir exists, put you script there, and type:
By convention a directory named "bin" is used for this. Some distributions arrange for the bin directory as a subdir of your homedir to be included automatically. This is done by some lines in your ~/.bashrc or ~/.bash_profile or maybe ~/.profile. These lines resemble somthing like:
# set PATH so it includes user's private bin if it exists
if [ -d ~/bin ] ; then
To have you custom dir "/home/yourname/myscripts" permanently in the PATH var. Add the following line at the end of your ~/.bashrc or ~/bash_profile:
FYI: You can also put "." in your PATH and then the current directory is searched, much like in DOS. Generally, however, this is not recommended, though I personally prefer it for my non-root development user.
e.g. put in your ~/.bashrc:
Or something of the sort. If you do put "." in your PATH, you should make it the last thing in the PATH.
